Nanoparticle Coatings for UV Protective Textiles

TAs the intensity of ultraviolet (UV) radiation increases every year, effective methods to block UV rays to protect human skin, plastics, timber and other polymer materials are urgently sought. Textiles serve as important materials for UV protection in many applications. The utilisation of nanoparticles to textile materials has been the object of several studies aimed at producing finished fabrics with different performances. This article reviews the recent advancements in the field of UV blocking textiles and fibers that are functionalised with nanostructured surface coatings. Different types of UV blocking agents are discussed and various examples of UV blocking textiles that utilise zinc oxide (ZnO) and titanium dioxide (TiO₂) are presented. Future challenges, such as wash-fastness and photocatalysis, are also discussed.
